Can anyone explain with example? How can I correct my site? I am very confused. I do not understand what is this file, which Google does not find on my site.
Josemon is right .. the google support itself having what is robots.txt file .. try googling it..
robot.txt is a file which is scanned first by the webcrawlers, when they access a website ..in this file we define, which directories should be indexed and which are not ..it helps to reduce the bandwidth problems due to webcrawler access to our website...for more info http://www.webconfs.com/what-is-robots-txt-article-12.php visit this
I assume you mean robot.txt
It's a file that tells search engine robots what information to gather
